Our traditional residential buildings pay attention to sitting north facing south; Indoor beds are usually placed in the east-west direction. Experts believe that sleeping with your head facing south or north and south is good for your health.
Because the earth is a big magnetic field, the magnetic lines run through the north and south. The water molecules in the human body are like a small compass, constantly swinging under the action of the earth's magnetic field lines.
When the poles of water molecules are in the same direction as the magnetic field lines between the north and south of the earth, the water molecules stop swinging and tend to be stable; When the polarity orientation of water molecules is different from the magnetic field lines between the north and south of the earth, water molecules will be unstable.
If people's sleeping direction is north-south, then the direction of water molecules, people's sleeping direction and the direction of magnetic lines in the north-south direction of the earth are the same, so people are the easiest to fall asleep and have the highest sleep quality. In the blood circulation system of human body, aorta and great vein are the most important, and their direction is consistent with the direction of human head and feet.
When the human body sleeps in the north-south direction, because the aorta and great veins are also in the north-south direction, and the water molecules are also arranged neatly in the north-south direction, the blood flow with water as the main component is the most smooth and carefree, and its inertia is conducive to reducing the occurrence of thrombosis through capillaries.
Therefore, the north-south sleeping direction has certain disease prevention and health care functions.
2. Go east and say:
Foreign scientists, on the other hand, advocate sleeping with head facing east, believing that head facing north often leads to insomnia and discomfort. Salada subrahmanyam, a professor of physiology at Madras Medical College, demonstrated this basic principle. She said: the weak interference of the earth's magnetic field will greatly change the electrical activity in the brain.
If you sleep with your head facing north, it will cause great changes in biochemical movement in the human body. The micro-pulse of magnetic field greatly inhibits the electrical activity of the brain, which makes people feel uncomfortable, irritable and irritable. If you sleep with your head facing east, you will feel a sense of peace.
3. Sleep with your head facing northwest and say:
Chinese medicine says that the human body should "stand pulse" and "stand qi" during sleep. This "standing" actually means that the direction of qi pulse in the body is consistent with nature, so that blood vessels will be unobstructed.
We know that the terrain of our country is high in the west and low in the east. Along the mountain and water potential, the direction of airflow is northwest to southeast. Chinese medicine suggests that people sleep with their heads facing northwest and their feet facing southeast, so that the pulse of human body is consistent with nature.
The second direction is that the head faces west and the feet face east, or the head faces north and the feet face south. As we know, the earth where human beings live is a huge magnetic field, and its magnetic lines pass through the earth's surface from the North Pole to the South Pole. When the human body is sleeping, the biological current channel is perpendicular to the direction of the earth's magnetic field lines, so the magnetic force of the earth's magnetic field becomes a strong resistance to the human body's biological current. In order to restore normal operation and reach a new equilibrium state, the human body has to consume a lot of heat energy to improve its metabolic capacity.
4. Spring and summer head east, autumn and winter head west said:
Regarding the direction of sleeping, the ancients put forward the view that "autumn and winter go west". For example, it is said in A Thousand Women's Cultivation in Daolin that "mortals lie in the east in spring and summer and in the west in autumn and winter", and "Remember jade algae" is quoted in Lao Lao Heng Yan: "Where they lie, they should lie in the east in spring and summer and in the west in autumn and winter".
The reason is that spring and summer belong to the sun, and the head should lie east; It is cloudy in autumn and winter, and the head should lie facing west, in order to conform to the principle of "nourishing yang in spring and summer and nourishing yin in autumn and winter".
Summary:
There is a saying that there is east, west, south and north, which makes everyone confused.
Still the first sentence: how to sleep comfortably!
